HYDROCARBON-MOTOR.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed April 14, 1915. Serial No.-21,314.

" of Detroit, Wayne county, State of Michigan, have invented certain newand useful Improvements in Hydrocarbon-Motors, of which the following isaspecification.'

This invention relates to hydrocarbon motors, and particularly to thecooling thereof. More specifically the invention relatest to a watercirculation system for the cylinder water jackets of a hydrocarbon motorin which the temperature of the water is automatically controlled by. athermostat or equivalent device. illustration of one embodiment of theinvention a twelve cylinder motor having two cylinder blocks of sixcylinders each arranged in V position is shown, but it will beunderstood that the invention is not lim-' ited to the exact form hereinshown but may be modified in various ways without departing from thescope of the invention;

One of the objects of the invention is to provide a simple and practicalautomatic control for the temperatureof the water of the cooling systemof a hydrocarbon motor.

0 Another object of the invention is to provide a cooling system for ahydrocarbon motor having two cylinder blocks, in which the temperatureof the water will be ,auto.

matically controlled and will be uniform in the two cylinder blocks.

Another object of the invention is to provide a simple and novel pumpmechanism and thermostat device fora hydrocarbon motor.

Another object of the invention is to provide a particularlyadvantageous-and novel arrangement 'of conduits and water circulationelements of a hydrocarbon motor.

Other objects of the invention will appear from the followingdescription, taken with the drawings, which form apart'of thisspecification, and in which: i

Figure 1 is a side elevation of a motor made in accordance with thisinvention, some of the parts being shown in section;

Fig. ,2 is a plan viewof the motor illustrated in Fig. 1;

Fig. 3 is a vertical transverse section substantially on the line 3-3ofFigs. hand 2;

Fig. i is an enlarged section through the thermostat chamber showing theparts in a different postion from that shown in Fig. 1;

As an Fig. 5 is a section through the pump mechanism takenlongitudinally of the driving shaft, and substantially on the line 55 ofFig. 6;

Fig. 6 is a vertical section taken transversely of Figs. 1 and 5substantially on the line 66 of Fig. 5;

Fig. 7 is a sectional view of another form of the pump and thermostat;

Fig. 8 is an end elevation of the pump and thermostat shown in Fig. 7

Fig. 9 is a sectional view of another form of thermostat unit; and

Fig. 10 is similar to Fig. 9 but showing a modified form of valveconnection.

Referring to the drawings, 10 represents the motor base or crank case,in which is mounted the crank shaft 11 in suitable bearings 12. A pairof cylinder blocks 13 are mounted upon and secured to the crank casewith the cylinder axes of the respective blocks in V relation. In theform shown,

as arranged vertically above the crank shaft. and driven thereby throughchain mechanism 17 or other suitable gearing. The

usual piston 18 and connecting rod 19 are shown, and the intake pipesare represented at 20 and the exhaust pipes at 21.

.the cylinders are arranged approximately 60 degrees apart, the motorshown being 21.12 Inlet and exhaust valves Each of the cylinder blocksis provided with a water jacket lhaving an intake opening 22 arrangedadjacent the middle of the block and preferably on the outer sidethereof, as shown particularly in Fig. 3. It will be understood that thewater jackets surrounding all of the cylinders of each block areinter-connectedso that they form practically a single water jacketaround the entire block of cylinders. Each block is provided' with anoutlet at either end, the front outlets indicated at 23 'and the rearoutlets at 24. Radiator means 25 are suitably mounted at the front endof the motor andconduits or pipes 26 connecttheoutlets 23 of thecylinder block w-aterjacke'ts with said radiator means '25. 'At the rearend of the motor there are branch pipes 27 which lead from the outlets24: to a bypass pipe or conduit 28. It will be understood that theradiator 25 may be of any suitable well-known construction adapted tocause a rapid radiation of the heat from the water passing downwardlythrough it. It is provided with an outlet pipe or conduit 29 which leadsrearwardly to a conduit 30 with which the bypass pipe 28 also connects.Referring particularly to Figs. 1 and 1, it is seen'that the portopening 31 of the pipe 28 into the conduit 30 is arranged just below theopening 32 of the pipe 29 into said conduit 30. These openings arecontrolled by a valve 33 which may be moved in the conduit 30 by meansof its stem 31 to cover and uncover the ports 31 and 32 above referredto. In the position shown in Fig. 1, the port 32 is practically closedand the port 31 is open, it being understood that the water entering theconduit 30 through the port 31 will pass upwardly through the valve 33.In Fig. l the valve 33 is in its lower position closing the port 31 andleaving the port 32 wide open. In this latter position of the valve thebypass conduit 28 is thrown out of action and the radiator means is inoperation.

Referring particularly to Figs. 1 and 3, it will be seen that a pumpmechanism 35 is arranged between the conduit 30 and the intak openings22 of the two cylinder blocks. A pipe 36 forms acommunication betweenthe pump mechanism 35 and the intake 22 of the right hand cylinder blockin Fig. 3, and

a pipe 37 leads from the pump mechanism through the crank case to theintake 22 of the left hand cylinder block of said figure.

In the form of the invention shown, the pump mechanism comprises asuitable double pumpcasing 38 in which a pair of spaced impellers 39 arerotatably mounted. These impellers are probably best shown in Figs. 5and 6 as are also their bearings -.t0 in the casing. The impellers aresuitably driven from the motor crank shaft by means of a shaft 41extending forwardly from the pump casing to the gearing at the front endof the motor. p

The pump casing 38, in addition to its connection with the cylinderblocks and crank case through the pipes 36 and 37 as above described, isalso connected to the. conduit 30 by the tubular part 12 which forms acontinuation of said conduit 30. It will be seen, therefore, that theconduit 30 forms a common intake for both pumps. It will be seen alsothat one of the pumps discharges into the pipe 36 and the other intopipe 37, but as both of them take the water from the conduit 30, thewater passing to the two cylinder blocks is of the same temperature.

Referring to Fig. 6, the pump casing is enlarged somewhat at one side toform a continuation of the intake conduit 30, and the valve stem 31extends upwardly into, this enlargedpart and is connected to athermostatic unit 43 of any suitable construction. It may be in the formof an expansible metal or, as shown in'the form of a plaited tubecontaining an expansible liquid or gas whereby the valve 33 through itsstem 31 is caused to change itsposition with relation to the openings 31and 32 upon a change in temperature of the water passing through theconduit 30. A rack bar 11 is secured at the upper end of the unit 13,and its cylindrical upper end it forms a guide for the unit 13 and valvestem 31.. The thermostat unit and valve are adjusted or positioned by asmall pinion 15 on a shaftlG engaging the teeth 17 of said rack. Saidshaft 16 may be moved by the handle 18 arranged on the outside of thecasing and a locking screw l9 secures the shaft.

It will be understood that the thermostatic unit 13 contracts with thecold and expands with the heat. Therefore, the valve 33 being set in theposition shown in Fig. 1 when the motor is cold, if the motor is startedand the pump thereby operated,- the cold water in the circulation systemwill pass through the water jackets of the cylinder blocks and out atthe rear end through the. pipes 27 and 28, through the port 31 and thevalve 33.

and flow over the thermostatic unit 13 and back to the pump. There willbe practically no circulation from the front end of the cylinder blocksto the radiator because of theclosure of the port 32 by the valve Asthere is practically no radiation inthe pipe 28, the water in the systemwill soon begin to heat up and thus expand the thermostat 13. As thethermostat expands,'it moves the valve 33 downwardly and begins to cutoff the port 31 and open the port 32. 1 In the normal operation of themotor the valve will probably remain near its lowest position, but thiswill of course vary with the effectiveness of the radiator means 25 dueto atmospheric changes. The positioning device l5, 16, is useful invarying the tempeiaturedegree at which it-is desired to operate themotor. A drain cock 50 is provided adjacent the valve mechanism toassist in draining the water system.

Referring to the form of pump and thermostatic mechanismillustrated inFigs. 7 and 8, it will be seen that the pump is substantially the sameas that illustrated in the other figures except that there is noenlargement for the thermostatic unit, the latter being arranged in aseparate chamber below the pump. There is'a similar tubular part 12 towhich is attached a casing 30 formed with achamber 30 in which is ahorizontally arranged thermostatic unit. 13 connected to a valve stem 31having valve 33 cooperating with port 31 and valve 33 and 29communicating with ports 31 and 32 respectively are also shown 1n l lg.4. For

cooperating with port 32*. The pipes 28 the purpose of holding the valve53 closed as long as possible after starting the motor cold so that itwill quickly heat up to normal temperature, the valves are so positionedthat the water pressure against them tends to hold valv 33 open andvalve 33 closed, thus by-passing the water until it is quite hot beforethe thermostat can act to expand and open the pipe leading from theradiator. Also, in the use of a thermostat which expands uponpuncturing, the radiator port 32 will be opened or left open as the casemay be, automatically in case of an accident to the thermostat.

In Fig. 9 a thermostat 4L3 'is used similar to that of Fig. 7, but thevalves are differently arranged. J Where comparatively higher waterpressures are used, or for other reasons, it is desirable to have thetwo valves balanced and interconnected. Thus the stem 84 is operativelyconnected through pin 84* and transverse slot M with a link 34 whichlink forms an interconnection between a balanced butterfly valve 33controlling the passage 31 in the pipe 28 and a similar valve 33controlling the passage 32 in the pipe 29. This link is so connected tothe valves that while one is opened the other is closed and vice versa,and the thermostat connection is such that, as shown in full lines inFig. 9, when the system is cold or the active element contracted, thevalve 33 will be open and thevalve 33 closed, and vice versa. Since bothvalves are balanced the water pressure does not affect the opera 1 tionof the thermostat.

In Fig. 10 the thermostat is so connected to the valves that the lattermay be independently and manually operated. In case of failure of properoperation of the thermostat or for any other reason it is desirable attimes to positively open the valve 33 and hold it open to permitcirculation of water through the radiator 25. Thus in Fig. 10 theconnection from the element 43 to the link 34 is a yielding one, theslot 3 3 being formed in a sleeve 34' sliding on the link 3& andarranged between springs 34 and stops 3%. i It will be seen that thenormal operation of the valves isthe same as in Fig. 9, but they may bemanually operated independently of the thermostat, one or the other ofthe springs 34; yielding for the purpose. The valve is manually operatedby a handle 33 secured to its stem 33 on the outside of the pipe 29 anda segment 33 permits of locking the valve in any desired position bymeans of the set screw 33.

Variousother forms of the invention may be devised and will fall withinthe terms of the claims, and I do not intend that my invention shall"be-limited to the exact constructions shown, these being by way ofillustration only.
